             Summary: RedeliveryPolicy:Exponential Backoff + NonBlockingRedelivery = too long delays
                 Key: AMQ-8617
                 URL: https://issues.apache.org/jira/browse/AMQ-8617
             Project: ActiveMQ
          Issue Type: Bug
            Reporter: Endre Stølsvik


Scenario on client:
 # Enabled RedeliveryPolicy with exponential backoff (keeping maximum redeliveries at > 1, e.g. default 6)
 # Enabled non-blocking redelivery
 # Receiving e.g. 100 consecutive poison messages (which eventually should DLQ after max redeliveries)

This will result in absolutely massive redelivery delays due to a logic bug.

The reason is that redeliveryDelay is a field variable kept on the ActiveMQMessageConsumer, instead of being a property on the message - or that the redelivery delay was calculated per message based on the redelivery count.

When consecutive messages redelivers multiple times, the redeliveryDelay field is continuously multiplied by the backoff multiplier, resulting in absolutely massive delays.

I'll submit a PR.
